INVESTIGATION ON NORTH AMERICAN TRAFFIC CALMING DEVICE SELECTION PRACTICES

Traffic calming provides a process for identifying and addressing existing problems related to speeding, excessive traffic volume, and pedestrian safety concerns on residential streets. Although several traffic calming devices have been installed in Asian countries for example in Japan and Korea; they have no distinct and methodical process for the device selection. The objective of this research is to illustrate a comprehensive review of North American traffic calming device selection process practices. The aim is to establish traffic calming device selection process guiding principles to be introduced in Japan. This research reveals that speeding is the most significant issue for installing a traffic calming device. The result explores that community support is the most important factor for the selection of a traffic calming device. The result shows that speed humps and speed tables or raised crosswalks are the most widely practiced devices.
